But anyway - lots of the time the gauges (stepper motors), or the sender goes bad. Back in the day that was a GM trait on high mileage vehicles - the bouncy oil pressure gauge. Nowadays with all the shoddy components they use, you can't be 100% sure without testing. If your concerned with the oil pump I'd get a real gauge & hook it up to the block for a true reading - only then can you rule out the oil pump.
